Chaos, Walker of the Wheel (Sicarius)

"Walker of the Wheel, captive to the maelstrom of hope and despair! Unleash the power of the chaos within you!"

- Meia, during her summoning.

The Sicarius Chaos, Walker of the Wheel is the 17th permanent Sicarius appearing in Mobius Final Fantasy. He first appeared on November 22, 2018, as a ★4 or ★5 challenge for advanced players.

As a "3rd Gen" Sicarius, Chaos has no ★1 - ★3 difficulties, so he is only available while Chaos is featured as the advanced adversary of the week.

Special elements
Chaos is an elementally sensitive Sicarius. He is surrounded by four swords, each with a different elemental boost, and uses them to absorb and release attacks!
 * Chaos shows up with four Elemental Counters,, ,, and -- each initially set with a count of 3.
 * Each time a player attacks Chaos with an elemental attack or ability, the corresponding boon will go up by 1.
 * Chaos will counter-attack each player with an elemental attack of the same element that player primarily used. The higher the count, the stronger the attack. Each such attack reduces his count for that element by 1.
 * If players break Chaos or equip a "Chaos Lieutenant" card, one counter will go away, and will not come back. Each time one goes out, that sword will stop glowing and Chaos will not cast any further counter-attacks of that element.
 * Breaking his or equipping Archkraken also removes his
 * Breaking his or equipping Archmarilith  also removes his
 * Breaking his or equipping Archlich  also removes his
 * Breaking his or equipping Archtiamat also removes his
 * If a counter reaches at least 7 (?), Chaos will unleash a powerful area attack Chaos Blade that uses all of the count in one element. Like a break, that element is "spent" and will not return.
 * If the totals across all elements are high enough, he'll hit with Hurricane, which uses up all of his counts.
